About this deal

However, on the whole, If you are choosing a dehumidifier for use in the normal living areas of your home, then a refrigerant model will be entirely suitable. The desiccant adsorbs the water vapor in the humid air, and the dry air, shown by the gray arrows, is vented back into the room. A desiccant dehumidifier will have a wheel coated with something like silica gel or lithium chloride that gently rotates, while a fan draws in air from the room and passes it across through the wheel. degrees Celsius warmer than the ambient air), you are likely to be using less energy on heating for your home. Such integration can improve performance by improving the vapor compression cycle's COP (by operating between closer temperatures), [12] and enhancing air mixing near the membrane.

If you’re looking for something to extract large volumes of moisture, operate in low humidity or at a low temperature then it’s a desiccant dehumidifier you’ll need.You might also know this as electronic defrosting as it uses a sensor to monitor the ice build up on the evaporator. A desiccant is a material that absorbs water and will be familiar to anyone who has ever found a small pack of crystals, labelled "silica gel", packaged with a camera, computer or some other product. As the wheel rotates the hygroscopic media passes through a separate isolated chamber where air is heated so the moisture passes back from the wheel to the air and is exhausted away. Defrosting using a hot gas mechanism is much faster and more effective than air circulation at lower temperatures so when you’ve got an application with an ambient below 15°C then this is the system to go for.

Peltier conductors are small, neat and compact so the dehumidifiers are much smaller than the other types, plus as they don’t use compressors or heating elements and only very small fans the electrical consumption of Peltier driers is a fraction of that used by refrigeration dehumidifiers.They’re single use and require regularly replacing, uneconomical and have no way of circulation the air so cannot really effect the overall RH level of an entire room.

The reason for the limited acceptance of desiccant dehumidification can be attributed to initial installation costs, the fact that operational benefits are not fully understood, lack of technology awareness, and company priorities, which are not focused on benefits of new technology. However unlike passive dehumidification mechanical desiccant dehumidification also uses heat for a process known as hot air regeneration.

With dehumidification you use the amount of water that is actually dissolved in the air and compare it to the maximum amount of vapor it could absorb at whatever temperature the room is, thus giving you the Relative Humidity, or RH level as it is more commonly known. An alternative design senses the impeded airflow and shuts off the cooling coils in a similar manner.
